I think you are both missing important point: classes which support context would be able to be used in "with" contexts"; Nothing would be more complex or slower - you'd only use it to make things cleaner (move code into class _enter_() and _exit_() methods, which would only get called (I presume) on with use anyway... If you have the code in one place instead of scattered, there is nothing slower or more complex - to the contrary.
I would agree with you that this could get overused in places (e.g. if it were used as "syntactic sugar") - but that is a different story. cvs reader and writer - I had trouble (had to "hack" a fix) with this in the registration system; I never provided a patch, because could not see a good, clean way to decouple application setup from gluon --- THIS is a way to do that. I'm pretty sure if I looked, I'd find a few (not many maybe, but a few) places this would be a good idea, solve existing problems. I think both of you need to just consider this a little more carefully, that's all... - Yarko On Mon, Jul 13, 2009 at 7:00 PM, mdipierro <mdipie...@cs.depaul.edu> wrote: > > I agree with Joe.
